TP40S - 200mm Bargraph Display

Supplier: Amalgamated Instrument Co

The TP40S series 40 segment 200mm bar graph display is designed for applications where good visibility is important. Large, high intensity LEDs provide a wide viewing angle.


The display has been designed to be wall mounted. An optional panel mounting kit is available if required. Scaling and alarm relay setup is achieved via pushbutton operation.

Input range is set via user selectable link settings. In addition to the standard mA and DC voltage inputs the instrument may be factory configured to accept inputs from 4 wire mV output load cells/pressure transducers.

A 18VDC unregulated transmitter supply is provided as standard on models with AC supplies. An optional isolated and regulated transducer excitation voltage is available to suit various sensors or transmitters. Two relays are included to provide high and low alarm outputs.

The face of the TP40S can be customised with a legend and a bargraph scale to suit the application. For example the display can be showing the contents of a tank as a percentage. The legend could be ”%” and the bargraph scale could be 1 - 100 with graduations of 10 (as shown in the illustration).
